ITEM 5. OTHER EVENTS
- --------------------

         On December 7, 2001, Credit Suisse Group and the Credit Suisse First
Boston business unit, of which we are part, released information on estimated
one-time charges, and expected fourth quarter operating results, for the Credit
Suisse First Boston business unit. Credit Suisse Group stated that the fourth
quarter continues to be challenging and that the Credit Suisse First Boston
business unit operating result is not expected to improve from the third
quarter. Many of the estimated one-time charges for the Credit Suisse First
Boston business unit will be taken at the Credit Suisse First Boston (USA), Inc.
level. We estimate that we will take one-time charges relating to our staff
reductions of approximately $400 million to $450 million. Approximately $350
million of the estimated one-time charges relates to bonus and severance
payments, guaranteed compensation and retention awards in connection with staff
reductions, a significant portion of which would have been recorded as
compensation expense in 2001 if such staff reductions had not occurred.
Approximately $50 million to $100 million of the estimated one-time charges
relates primarily to planned fixed asset and sub-leasing costs of exiting
certain premises.
